IMPORTANCE A new analysis method called permutation of pointwise linear regression measures the significance of deterioration over time at each visual field location, combines the significance values into an overall statistic, and then determines the likelihood of change in the visual field. Because the outcome is a single P value, individualized to that specific visual field and independent of...

To evaluate the efficacy and safety profile of Kahook Dual Blade ab interno trabeculectomy combined with phacoemulsification compared to stand-alone conventional cataract surgery. A single-center longitudinal, randomized controlled trial was conducted. Patients older than 18 years coexisting open-angle glaucoma or ocular hypertension were invited participate. Preoperative postoperative clinical...

The pioneering work of Stiles provided a means of psychophysically isolating and measuring the sensitivity of individual color vision mechanisms through the two-color increment threshold procedure. Basically, this approach involved decreasing the sensitivity of some color vision mechanisms (termed π mechanisms by Stiles) by using a chromatic adapting background light, and then measuring the sen...

PURPOSE To determine the magnitude of the homogeneous, LF(Ho), and the heterogeneous, LF(He), components of the long-term fluctuation (LF) in glaucoma suspects and in stable primary open angle glaucoma (POAG) patients undergoing short-wavelength automated perimetry (SWAP) and to compare the magnitude of the SWAP LF components with those elicited by standard white-on-white (W-W) perimetry. MET...
